XI-5-8 Friction part-2 (2015) Pradeep Kshetrapal Physics

[@manalipatil2478]

His lecture is like knowledge river flowing... Beautifully,peacefully and purposely.

[@jahnaviuppala1047]

the concept of flat and grooved part was awesome sir ...thnqq!!!!

We know that limiting friction does not depende on surface area......But in tyre case .....We thought that if there is no dust particle be them ....Then friction is more in plane surface than rugged surface due to more surface in contact..............Is that means kinetic friction depends upon area....Pls make clear sir...

sir mai abhi just coaching se 6 hrs ka leacture attend karke aaye but phir bhi aapke leacture dekhne ka energy hai and man karta hai itne zydsa frustuation ke baad bhi mai last sunday bhi 6 hrs ka leacture attend ki thi phir aapke leacture 4 hrs tak dekhi thio phir bhi bore nhi hua thas aap leacture hi aise banate ho sir time ka pata hi nhi chalta

[@venetakumar9688]

Sir, in the sum at 43:00 isn't it a connected body? why is only 50kg mass considered for finding the acceleration and not (50+15)kg?

[@alphasharma8933]

Veneta Kumar because 15kg mass or 150 N (effort) is used to pull the 50kg (load)

[@ShawnDypxz]

+Alpha Sharma You are wrong. Actually Veneta Kumar is right . Because it's a system both the mass will accelerate at constant value of a. Also Sir has forgotten to mention one thing on this numerical. Actually when limitinng friction is overcame , kinetic friction acts into play which is less than the value of limiting friction and therfore the net force will be more and Since it is system, Acceleration will be the (150 - (muk *500))/(50+15)

[@asadshaikh4853]

at 2.32 you said friction is a reaction force of applied force, but Sir action and reaction force act on different bodies , not on the same body. Can you please explain. Thank You.

[@navdeeepdhingraa9696]

Love the way u teach ... May God Bless U Sir

[@prititayal6164]

Sir, Are Notes of Lesson, available in PDF format. Pls suggest. Tks

[@prajwalkunder2760]

Sir is it always true that friction always opposes the motion

[@preetimath5110]

Friction always opposes the intention of motion.

[@rishabhmishra822]

No sometimes it allows the motion Example walking🚶🚶🚶🚶🚶🚶🚶🚶

Greatest teacher on this planet

[@asadshaikh4853]

angle of friction part is superb

[@AmandeepKaur-ry3nh]

why kinetic friction does not depend upon velocity plz tell me sir

[@ashukhandwe8259]

lucky students

[@mdhussain363]

wha!!!!!!!!! mja aagaya ... thank you sir for this lecture

[@akhileshsinghyadav4440]

sir in wall condition force is not balanced becouse f balance to normal reaction but mg is not balanced than how body is not accelerating pleasse explain

[@s.s3546]

same question.? sir plez tell?

[@jayashagrahari611]

bro the intention of motion is downward which is counter by friction .....just imagine it

[@anmolYo]

THANKS SIR

[@angeshkumar334]

sir you are doing great job.... Thanks....

[@ramkumaryadav9260]

sir u r best of best teacher

[@rahulsingh-sg8vr]

Ek doubt hai sir... Agar car start hogi toh starting me static friction aayega uske baad kinetic friction aayega... Iss chiz me bahut confusion hai sir isko clear kr dijiyr... Thankyou

[@mohdamaan7178]

Kya samjhaya hai maza a gaya

[@dr.vikaskumar6571]

sir apne yaha par jo effort or load ka question karya hai usme net force dono bodies ko accerlaration dega ya fir sirf ek body ko .yaha par apne sirf net force ko ek body ko accelerate kiya hai ye mujhe confuse kar raha hai .sir plzz clear my doubt

[@simminaagar3556]

dono ko

[@mohdamaan7178]

Who is doing sir lecture for basic concepts of jee main only

[@TheRedArmyChannel]

sir, when will you release english subject lectures.?

[@sunnyrayxo]

he is a physics teacher dumbo why will he do so???

[@jatinrathore3997]

looool

[@umamaheshwary6584]

Excellent explanation thanks sir

[@Gorv_g]

KZbin bhi kaam ki cheez hai☺☺☺😝😝😝😝😝

[@prititayal6164]

Sir any pdf is available of your lectures??

[@AmbrishKumarAJE]

excellent teacher

[@sandeeptiwari3655]

Nice explanation
